can you upgrade Ticketmania tickets?

[TiffJ]

We just ordered the 7 day expiry MYW tics from Ticketmania. Could we add the plus feature if we decided we wanted it once we got to WDW? Thanks!

Yes you may add plus options, non-expiration, or even an 8'th, 9'th, or 10'th day, within 6 (13?) days of first usage.

Currently you pay the difference between the gate price of what you want and the gate price of what you have. Do this at Guest Relations just outside or just inside any park.
